Decorated Research!

08.06.2016

Since many years we research in the field of centrifuges like our new GP Series or the Z 11 for Nano Particles. Additionally we also develop new ways of feeding our de-oiling systems with robot technology or autonomous driving vehicles for the transport.

Get to know our new Technologies and contact us: info@cepa.de.

CEPA Email-Server presumably hacked

Despite of extensive safety efforts of our company network we were a victim of the Locky virus some weeks ago. Now we fear that our mail server was hacked and that eMail will be send in the name of our employees.

Do not open files, if you do not expect a mail from us. Never open zip-files! We only send pdf-files.

With kind regards,

Handling oil recovery efficiently

“What better way could there be to protect the environment and save costs?” remarks Markus Korta, Otto Gantner Plant Manager at Rheinhausen, where the CEPA FLEXOMAT is used for efficient de-oiling of metal chips.

On site at Otto Ganter GmbH & Co. KG - A leading manufacturer of handles and standard parts, and a long-standing CEPA customer.

Two high-performance centrifuges of the GZ series are in use at the Rheinhausen plant, separating metal chips from the oil used as coolant and lubricant in the automatic lathes.

Since the FLEXOMAT went into operation, the process of recovering the precious aluminium, stainless steel and steel chips has been as profitable as it has been smooth. Recycling the cleaned metal residue brings in hard cash, as does recovering oil from centrifuging, because it can then be returned to the production process and minimises the need for purchases of fresh oil.
A group of prospective FLEXOMAT customers from Sweden is viewing the system in action at Ganter and is impressed at its efficiency. “In the FLEXOMAT, the chip stays in the same container throughout the entire process, from the moment it is formed. Individual centrifuging times that depend on the material are possible in this system. All manner of chip shapes, including endpieces and coarse particles, are centrifuged straight off without any further crushing or grading. Drip-free and always separated,” explains CEPA sales member Bernd Leibold. The FLEXOMAT is tailored individually to requirements on the ground. A successful concept for using raw materials economically based on engineering expertise stretching back more than 90 years.

Visibly impressed by efficiency: prospective customers inspecting the FLEXOMAT in action at Ganter.

A doubly profitable economic factor

“The new plant is not yet running at full capacity. At the moment we get through 300 litres of oil per day. At a cost of EUR 2.50 per litre, that means Ganter is already making a quite appreciable saving of EUR 750 every day,” explains Markus Korta. The oil can be returned straight to the processing machine. The de-oiling system is rapidly paying its way and has a very long operating life.
More modern processing machines require highly pure oil. Here too, the oil recovered by the FLEXOMAT system can be used. Just one intermediate step is needed: CEPA cleaning centrifuges perform the final cleaning of the recovered oil.

Separating even minute particle systems

Universities and research institutions use CEPA high-speed centrifuges in their research work

Compared to laboratory centrifuges, high-speed tubular centrifuges are already capable of separating larger quantities of solids from suspensions. And in batch mode, up to several litres of solids can be harvested at a time by making use of such centrifugal forces.

In many laboratories, the use of centrifuges with cells is an established method of separating even minute amounts of just a few millilitres. The challenge is how to separate much larger amounts in a production process. CEPA tubular centrifuges do that very efficiently.

Specifically in the nanoparticle range, there is a trend towards ever smaller particle systems with new physical characteristics. Very long dwell times of up to several hours or immensely high forces such as those encountered in an ultracentrifuge result in complete separation of phases by appropriate inertia forces, using classic centrifuge technology. However, different methods are needed for separating large quantities or where additional tasks are involved, such as the classifying of particles. Here, high-speed tubular centrifuges are a highly efficient instrument for separating usually weakly concentrated suspensions. The operating principle, which remains as simple and effective as ever, permits effective modelling and therefore allows the separating results to be predicted accurately. Various publications demonstrate the high predictability of processes in tubular centrifuges. The results obtained with CEPA centrifuges have also impressed the researchers at the Fraunhofer Institute for Silicate Research ISC in Würzburg. The solid matter to be separated may range from minuscule amounts of 250 millilitres to up to 10 litres. For a solids content of around 2 % to 5 %, these centrifuges are suitable for operating in batch mode to process anything from a few litres to several cubic metres of suspension.

“The wet-chemical production of nano and microparticles in dispersion is a highly advantageous way of customising particles as the building blocks of composite materials.
But the challenge is that such particle dispersions can usually only be produced with a low solids content by weight. A much more promising approach is to use CEPA high-performance centrifuges for a higher solids content. The semi-continuous processing method in particular means CEPA centrifuges can process amounts of particles that also make them suitable for use on an industrial scale.”
